Read MetaTrader 5 log files programmatically to access Print() output from indicators, scripts, and expert advisors. Implements dual logging pattern where Print() statements go to MT5 logs (human-readable) and CSV files provide structured data for validation.

Triggers - check logs, did it work, Experts pane, Print output, runtime errors, debug output. (project) Source: terrylica/mql5-crossover.
